ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

Energy storage systems could be integrated with nuclear power plants to increase flexibility and potentially enhance revenues. This session will cover energy storage technologies that could couple to various coolant temperatures (medium- to high-temperature) or be integral to a plant's design. Energy storage classes include, but are not limited to, electrochemical batteries, mechanical compression/liquefaction of fluids, gravitational potential energy, heat storage materials (solids, liquids, gases; single- and multi-phase fluids), and power-to-X/synfuels.
